Hoth Bricks posted a leaked video of the third and final episode of The Yoda Chronicles up on their YouTube page. The episode isn't scheduled to air until later this year. Wookiepedia has the air date pegged for November 28, 2013 but cites no source for reference and no formal announcements have been made otherwise. The video is in glorious 240p quality low resolution, so your viewing enjoyment may be compromised.

I can confirm the November 27 air date on Cartoon Network. The first two episodes will be shown as well. The Phantom Clone, Wed 11/27 7:00 PMMenace of the Sith, Wed 11/27 7:30 PMAttack of the Jedi, Wed 11/27 8:00 PM, 11:00 PM, and Fri 11/29 2:00 PMAll times ESTFunny that the third episode is titled Attack of the Jedi, didn’t Lucas turn down that title for episode VI in favor of Return of the Jedi, because it didn’t sound like the Jedi way?
